Diagnóstico da ocorrência e impactos ambientais do Caramujo Africano (Achatina fulica) em Laranjal do Jari - AP

Abstract

The work addresses the problems of the African snail (Achatina fulica) in Laranjal do Jari, AP, focusing on its characteristics, associated diseases, distribution and impacts in the area and lack of control and prevention. Also notable is the lack of local studies on the impacts of the African snail. This species is described as a tropical African mollusk. Its spread is worthy of concern because it has been recognized as a threat to agriculture and the reduction of global biodiversity. Contamination is mainly due to inadequate management of snails in vegetable gardens and orchards, which can spread traces of the worms they host. The African snail is hermaphrodite, reproduces quickly and its introduction into Brazil has a controversial origin, linked to voluntary and accidental events in the 80s and 90s. Originally intended for human consumption, the species became an environmental problem when it was released in places inadequate. present in all Brazilian states. In relation to Amapá, climatic conditions favor the survival of African snails and the lack of basic hygiene services promotes their spread. The consequences include damage to biodiversity. Degradation of local forests and competition for resources with native species. Environmental problems are also observed in entertainment areas and courtyards. The research problem on this topic includes gaps in local studies on the impacts of the African snail, highlighting the lack of control and prevention of this species. Difficulties encountered include economic losses for farmers and risks to health and the environment due to worm transmission. The objective of the research is to document the occurrence and environmental impact of the African snail in Laranjal do Jari. The methodological procedures include a bibliographic review on species, distribution and environmental impacts, followed by field data collection, including interviews with residents and collection of samples in different neighborhoods. The research seeks to identify gaps in local knowledge about the African snail in Laranjal do Jari, providing information for future studies and contributing to the planning of a future management plan.
